i don't have $$$ for this (its for a friend) so if you want to help out it would have to be for free.
my friend drives an older Jeep Cherokee 2dr so this is an suv. inbetween the wheel-wells is 40". from the floor to the top of the seats is 18", and he wants to keep its relatively shallow (~7" internal depth).
the sub is a 13kv.2 which has a 5.75" mounting depth.
eD recommends 1.0 cft sealed, and 1.8 cft ported tuned to 35 Hz.
i'm thinking something like (internal dims) 37"width x 15" high x 7" deep, tuned to 30 Hz.
would someone be interested in designing a box for us? we're building it tomorrow. i still haven't grasped the concept of designing ported boxes, but sealed i can do. so if nobody can help w a ported box we will just do sealed.
